Get a Prusa but maybe not the mini unless you can’t expand your budget or very tight on space. Some of the big limitations of 3D printing is size and speed. You claim to not care about speed, but trust me, you will. In terms of size, a smaller print volume really limits what can be printed. Some will claim that it’s no big deal because you can glue pieces together and that is partially accurate, but at some point you’re just going to want to print something in one piece and not have to endlessly assemble it from many small pieces. If you have the space and budget get the larger Prusa model.
